General Warnings

This section contains general warnings statements regarding the use and maintenance of the
Fresenius 2008K hemodialysis machine. It is not a complete summary, and additional
warning statements specific to pertinent topics can be found within this manual.
Water
Warning! Connect water inlet according to the specifications for the machine. For further
information, see Appendix B, "Machine Specifications." The water used must meet
AAMI standards for water used in hemodialysis (currently RD62:2001). The correct ionic
concentration and bacterial quality can generally be achieved in the dialysate only with
treated water. Be sure that all specifications are satisfied. The water source must be
monitored periodically to detect fluctuations in water composition and quality that could
have an adverse effect on the patient or dialysate delivery machine. Particular attention
must be taken for chemicals such as aluminum, chlorine, and chloramine, as these
chemicals can cause complications in dialysis patients.
Warning! Comply with all local regulations in respect of separation of devices in the
water supply in case of back siphonage; an air gap must be created between the machine's
drain line and its drain.
Concentrates
Warning! The specific acid and bicarbonate concentrates, including the sodium,
bicarbonate, and electrolyte compositions, must be prescribed by a physician.
Warning! Many concentrate types are available for use in dialysate delivery machines.
Concentrates contain various amounts of dextrose, potassium, calcium, sodium, chloride,
magnesium, and other components. Most concentrates are designed as a two-part system
of acid and bicarbonate solutions which are mixed in the machine with water. Even within
the subgroup of bicarbonate type concentrates, there are at least four methods of
compounding the solutions. Each of these methods requires special calibrations or setups.
Certain methods are not supported. It is mandatory that the acid and bicarbonate types be
matched to each other. Be sure to use compatible solutions, labeling, and setups. These
setups include machine calibration, special adapters for certain concentrate types, correct
setting of concentrate option, and labeling. Failure to use the properly matched solutions
and machine calibrations may allow improper dialysate to be delivered to the patient,
resulting in patient injury or death. Verify composition, conductivity, and pH after
converting to a different type of concentrate.
Warning! Connection to a central acid or bicarbonate feed system requires the installation
of certain mechanical parts. Contact Fresenius USA for more information.
